Each release, you can choose different types of installation images to download: DVD and Network. DVD image contains all packages needed for installation and is perfect for offline installation. Network image is very small and downloads system and packages from online repositories.

You can write installation images to either DVD/CD disks or USB sticks. Always keep an installation media in case you need to rescue system.

The installation can take some time (well over half a hour) to detect some hardware combinations so be very patient during initial driver install from boot media (green line at bottom of screen reaches 100% well before all drivers installed) as you might think you are dealing with an installation failure.
